0 该延时继电器模块相比常用的继电器模块功能更全面、调节使用起来也更便捷。几乎可以应用于大多数专用应用设计中，如调整AC-DC负载大小等。具体介绍如下：硬件特色 Recommended load rating: 24 V DC/40 VAC, 5 A (10 A, normally-open, only). Screw terminals for relay contacts. DIP switches to set timing. Power indicator and relay state indicator LEDs. On-board 5 V regulator; runs from 7-15 V DC, or can be run from 5 V directly. Screw terminals for trigger and input power. Location for optional DC power barrel jack. Pre-programmed AVR Microcontroller (Atmel ATtiny2313A), with 6-pin programming header Standard timing features: Time delay can be set from 1 second to 31 hours. Time delay is set by DIP switches; no need to guess and check timing with an adjustment dial. Auxiliary cancel-trigger input, halts operation immediately. Can be triggered by any low-going signal, or external button, switch, or coin acceptor. Versatile operating modes: Can be run as a one-shot or repeating (automatic cycling) timer. Can be configured to cancel the trigger if a second trigger input is received. Can be set to automatically trigger at power-on. 延时继电器实物展示：继电器.png (328.06 KB, 下载次数: 0) 下载附件 4 小时前上传所需材料清单截图：材料清单.png (32.73 KB, 下载次数: 0) 下载附件 4 小时前上传 3
